Thereafter, an electrified probe terminal, which includes an absorbent material saturated with an electrode solution, is touched directly to a micro-area of skin within the localized treatment area while maintaining a close association between the electrified probe terminal and the ground terminal. Therefore, the electric current path between the probe and the ground is not a substantially greater length than the width of the localized treatment area. The electric current causes electrolysis of the hair follicles in the micro-area being treated. Thereafter, the electrified probe ...
